CAR-WINDOW.

To all whom it may concern:

Be it known thatI, ALFRED H. NEWPHER, a citizen of the United States, and resident of Chicago,-county of Cook, and State of Illinois, have invented certain ne'w and-useful Improvements in Car-Windows, of

metal window sash and is especially adapted for use in connection with the sashes of railway cars.

. The object of the invention is to provide improved means for securing glass within the sash frame.

The invention consists in a structure such as is hereinafter described and illustrated in the accompanying drawings, in which,

Figure 1 is a detail elevation of a railway car window; Fig. 2 is a detail section on the may be of any desired form which v; ill provide a seat for the glass plate or pane 11.

'line 2-2 of Fig. 1, and, Fig. 3 is a detail section on the line 33'of Fig. 1.

The several bars constituting the sash ,The invention is shown as applied to a sash frame of sheet metal. The side bars 10 are substantially'tubular in form, the sheet of i which each is composed being folded so as to form an inst'anding flange 12 which constitutes the shoulder for the glass, the outermargin of the bar being shown as somewhat flaring, its edge being slightly concave, as shown at 13*. A longitudinal bar v13 is fitted within the chamber of the tube and -may be secured in place by any suitable -means, as brazing. To the inner face of the side bar 10 there is securedaclamping plate,

14, preferably by means ofrscrews entering the bar 13, this plate overlapping the glass, itsinner margin being bowed outwardly to form an alcove or pocket for the accommodation of a cushioning strip of rubber, or like material, 15, this strip being provided with a lip 16 which extends inwardly between the inturned edge of the plate and the glass, a

Specification of Letters Patent.

Divided and this application filed April 3,

The top rail of the sash (not shown) may be substantially identical in form with the side bars, but the dovetail configuration of its outer margin need not be followed. The bottom cross-bar of the sash is also of sheet metal but is somewhat wider than the side bars. Its lower face is formed by so folding the sheet of metal as to provide a channel 17 dovetail in shape, and within this channel is fitted a rib 18, of complementary form, Of a rubber cushion 19, which forms the bottom edge or sill engaging foot of the sash. The inner wall of this lower cross-bar is bent inwardly, as shown at 20, and above this bend it is looped outward to form a lip 21 extending the entire width of the sash and thus providing a grip by means of which the sash may be raised and lowered. These details form no part of the present invention, and may be varied as desired.

Preferably the inner edge of the sheet of metal of which the lower bar is formed terminates immediately above the lip 21, a

clamping plate 22 being applied immediately above this edge and Overlapping and securing the glass 11. This clamping plate may be secured by means of screws 23 entering blocks 24 fixed within .the chamber of the bar, and is bowed outwardly adjacent its upper end, as shown at 25,.to provide a heading for the cushioning strip 26 of rubher or similar material, which bears directly upon the glass and has an upstanding lip 27 interposed between the glass and the edge of the bead. In practice the clamping plates 14 for the sides and top, and '22 for the bottom of the sash may be united to form a' continuous frame.

I claim as my invention In. a window, in combination, a sash having a seat for glass, a glass plate fitted to the seat, a clamping plate secured to the sash and overlapping the glassand having anyalcove in its inner face, and a cushion located within the alcove and bearing against the glass.
